"He worked for me last summer on a job, a construction job. He was a neighbor. He lived less than a block behind us for a year," Horton said.

On Tuesday, searchers used horses, all-terrain vehicles, dogs and a patrol helicopter to scour the small town.

"We are going to exhaust every lead that comes in," said Troop D Public Information Officer Sgt. Jason Pace of the Missouri State Highway Patrol said.

Missing Girl Taken on 1st Day of School

Horton was at the park with her sister and friends celebrating the end of her first day of the new school year when witnesses reported seeing her get into an SUV.

The girl's father said he was told the driver of the SUV was asking children at the park for help.

"He was whining he couldn't find his daughter. He had a missing child. He asked the girls in the park to help him," Horton said. "My oldest daughter walked up to his vehicle. That's when she was abducted."

Police said they stopped a similar vehicle 90 minutes later and arrested Bourne, who was driving alone.

Bourne was being held in the Barton County Jail on a $1 million bond. He had not entered a plea.
